OF CHICAGO, ILLINOIS.

RADIATOR.

Applicationled April 1,

To all whom t may concern.'

Be it known that I, IsADoRn S. ZrrLrN, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inRadiators, `of vwhich the following is a specification.

My invention relates to improvements in radiators especially Vadaptedfor use on au tomobiles or the like, 4and has for its object theprovisionl of an improved construction Vof this character having specialprovisions therein for efficient air circulation, and strength andrigidity of construction, the present invention being an improvementover that disclosed in my prior application filed April 21st, 1919,Serial No. 291,613. y

Other objects will appear hereinafter.

lThe invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best. understood by reference to the accompanyingdrawings forminga partv of this specification, and in which, f y 4 Fig.1, isa front view of a radiator embodying the invention, V

Fig. 2, an enlarged detail horizontal partial section taken on line 2 2of Fig. 1,

Fig. 3, an enlarged vertical section taken on line 3-3 of Fig. 2, j

Fig. 4l, an enlarged front view of la portion of the radiator proper,and

F ig. 5, an enlarged plan view of a section of one of the metal sheetsemployed in the radiator. y

The preferred form of construction, as illustrated in the drawings,comprises adj acent copper sheet-s 6 bent into zig-zag form and arrangedtogether in pairs in the usual Y way to forni vertical zig-zag watertubes 7',

as indicated, the forward and rear edges of each pair of sheets 6beingbrought together and soldered Vat 8 to close the front and rearsides of said water tubes. Thev individual tubes thus formed are alsobent at their forward and rear edges at the points 7, where their zigzagforni bring them adjacent each other so as to bring the edges of thetubes proper together when assembled in theradiator. The zig-zag watertubes thus formed 1920. Serial No. 370,450.

are secured together inthe radiator in the,l

usual way, to form horizontal air passages 9 therethrough to permit ofthe free' passage- A' of air through theradiator and to bringtheportions 7, of the forward and readward edges of adjacent tubes intoContact With each other. `The forward. and rear edges of the assembledradiator tubes are then dipped in solder in the usual way, to securethetubesy in place, and the body thus formed is assembled into the radiatorin the usual way.`

The sheets 6 are provided with laterally vertically extendingvprojections 10 and11,`

arranged to register with those vin adjoining sheets on the oppositesides of the air passage 9, the set of ribs 11 being provided with in--dentations arranged and adapted to'receive Y joining sheet on theopposite side of the air passages, this arrangement serving to properlyposition the water tubes apart to permit of freeV vertical. circulationof the air between them, and also serving to definitely position saidwaterv tubes with relation to each other to facilitatethe assemblingthereof and also to increase the rigidity and durability oftheconstruction.. By this arrangement it will be observed thatv a verticalcirculation o-f air, as Well as a horizontal circulation thereof, ispermitted through they radiator, thus adding to the cooling efficiencythereof, and that the corresponding projections 10 on the adsov v astrong, rigid and durable construction is provided.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation andk modification without departing from the spirit of theinvention. 1 therefore do not wish to be limited to the precise detailsof co-nstruction set forth, but desire to avail myself of suchvariations and modications as come within the scope of the appendedclaim.

Hari/ing describedniy invention, what I claim as new and desire tosecure by Letters Patent iszj,

A radiator comprising adjacent sheets of material bent and securedtogether to form water tubesV and air passages, said sheets beingprovided with registering inter-locking g Y 1,44e,e1e
